Lately my daughter has been really interested in time, days, months and years so I was searching for a tool to help her visualize and understand. I found a wonderful tool on www.snapfish.com that allows you to create a calendar with pictures of your children, family members, etc. This has been really helpful for her and she LOVES looking at all the pictures. We have a picture of each family member on their birthday, a picture of our daughter for her first school day, Halloween pictures, Christmas and so on. With this tool, she is really excited about learning all about time and asks me every morning to cross off yesterday and tell her what day of the week and month.
